Summary

SaSG GmbH & Co. KG

Germany · AI-generated

hosting business it-services

SASG is operated by SaSG GmbH & Co. KG.

What it's used for

  • The address space carries hosting and IT infrastructure services, evidenced by netnames such as DE-SASG-20090722 and SASG-IASCHERER-PI-NET, and reverse DNS entries like bbag-xgw1.ush.de.sasg.net and culutph05.cs.sasg.de.
  • The AS announces 11,776 IPv4 addresses across 6 prefixes and 1 IPv6 prefix, while maintaining 107 observed neighbours; this ratio indicates a transit or peering-heavy role rather than a pure access network.
  • Traffic from this AS consists of web hosting, server solutions, and individual software development endpoints for business clients in Germany.

Notable

  • Registrants for the five largest prefixes are consistently SaSG GmbH & Co. KG, while the smallest prefix 91.217.36.0/23 is registered to Juergen Scherer under the netname SASG-IASCHERER-PI-NET.
  • The company was formerly known as "SaSG Internet Services" before being renamed to SaSG GmbH & Co. KG.
  • The inventory includes a mix of /20, /21, /22, and /23 blocks, with the largest being 95.142.64.0/20.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 436 networks and 1,771 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
